The state of water is determined by the temperature. Every state has its own set of physical characteristics. Solids, liquids, and gases are the three common states of matter.
Figure 1: (PageIndex1) Plasma is often added as a fourth state to the standard classification of matter into three classical states. Quartz (solid), water (liquid), and nitrogen dioxide (gas) are shown from left to right (gas).
A physical property is the state in which a substance exists. At room temperature, some compounds (such as oxygen and carbon dioxide) exist as gases, while others (such as water and mercury metal) exist as liquids. At room temperature, most metals are solids. In any of these three states, any material will exist. Figure (PageIndex2) depicts the molecular differences between solids, liquids, and gases. A solid has a defined volume and form, whereas a liquid has a defined volume but no defined shape, and a gas has none.

Temperature changes may cause substances to change phase. Most substances are solid at low temperatures; as the temperature rises, they become liquid; and at even higher temperatures, they become gaseous.
Melting is the transformation of a solid into a liquid. (An older word you can come across is fusion.) Solidification is the result of a liquid turning into a solid. The temperature at which a pure material melts (also known as the melting point) is a property of that substance. The transformation of a solid into a liquid necessitates the use of energy. To transition from a solid to a liquid, any pure substance requires a certain amount of energy. The enthalpy of fusion (or heat of fusion) of the material is denoted by the symbol Hfus. Table 10.2 “Enthalpies of Fusion for Various Substances” lists certain Hfus values, which are believed to be for the melting point of the material. Since the unit of Hfus is kilojoules per mole, we must know the amount of material to determine the amount of energy involved. The Hfus is always a positive number in the table. It can, however, be used for both melting and solidification processes as long as you remember that melting is always endothermic (i.e., H is positive), while solidification is always exothermic (i.e., H is negative).

Students should be able to ‘explain the behavior and properties of materials in terms of their constituent particles and the forces that keep them together’ at this stage (VELS standards Level 6).

The ability to draw the normal static configurations of particles in solids, liquids, and gases does not, however, imply that students have a completely particulate view of matter. According to research, many students this age and older also have a variety of alternate conceptions regarding particles that are difficult to dispel. They also misunderstand the very small size of particles, ascribe macroscopic properties to microscopic particles, struggle to understand particle motion in all states of matter, and have trouble understanding forces between particles. Driver Analysis (1987) Many students who understand that matter is made up of particles also believe that particles can change form (from solid to liquid), burst, burn, grow, change shape and color, or shrink. Students visualize atoms, molecules, and ions as small ball-like structures (possibly due to the way the knowledge is presented), which leads to a mix-up of particle properties and the macroscopic existence of the materials they make up. Happs (research) (1980) These concepts are also discussed in the main concept.

One of the four fundamental states of matter is strong (the others being liquid, gas and plasma). A solid’s molecules are tightly packed and have the least amount of kinetic energy. A solid’s structural rigidity and resistance to a force applied to its surface are its distinguishing characteristics. A solid material, unlike a liquid, does not flow to take on the form of its container or extend to fill the entire available space, as a gas does. A solid’s atoms are kept together either in a normal geometric lattice (crystalline solids, such as metals and ordinary ice) or in an irregular lattice (an amorphous solid such as common window glass). Solids cannot be compressed at low pressures, while gases can be compressed at low pressures due to the loose packing of the molecules in a gas.
